Reciprocal effects of health and labor force participation among women: evidence from two longitudinal studies.

Longitudinal data were analyzed to provide information concerning the effects of health on women's labor force participation and the effects of labor force participation on women's health. The data were from a representative national sample of middle-aged women and a representative sample of women from Alameda County, California. Significant relationships were observed between self-reported health and subsequent changes in labor force participation. Women who reported poorer health were more likely to leave the labor force and less likely to join the labor force. In contrast, no significant relationships were observed between labor force participation and subsequent self-reported change in health. (These latter relationships could be tested only for married women in the national sample.) In conclusion, our analyses provide substantial evidence that health affects women's labor force participation (the healthy worker effect). In contrast, we did not find evidence that, on the average, labor force participation has either harmful or beneficial effects on the general health of middle-aged married women in the United States.

Alkalinization of chloroprocaine for epidural anesthesia: effects of pCO2 at constant pH.

Increasing the pH of 2% chloroprocaine (CP) with sodium bicarbonate to pH 7.7 hastens the onset of epidural analgesia. The purpose of the present study was to determine the effect of pCO2 on the onset of epidural analgesia with CP buffered to a constant pH 7.7. Four groups consisting of ten patients each were studied: C, control, commercial CP (pH 4.35); B, CP buffered with sodium bicarbonate (pH 7.7); T, CP buffered with tromethamine (pH 7.7), and BT, CP buffered with sodium bicarbonate and tromethamine (pH 7.7). All epidural catheters were placed at the L2-3 or L3-4 interspace using a loss-of-resistance technique with air with each patient in a sitting position. The pH and pCO2 of each local anesthetic solution were measured as well as the onset and duration of analgesia. The study groups did not differ with respect to demography or entry characteristics. There were intergroup differences in the pCO2 values of the study solutions as follows: Group 1 (C), 11.8 +/- 1.5 mmHg; 2 (B), 113.0 +/- 1.4 mmHg; 3 (T), 3.0 +/- 0.3 mmHg, and 4 (BT), 74.1 +/- 1.0 mmHg, respectively. The time to the onset of analgesia was significantly faster in Group 2 (B; 2.7 +/- 0.8 minute), while the onset of analgesia was significantly slower for Group 3 (T; 5.4 +/- 0.4 minute) than either Group 1 (C; 4.2 +/- 0.8 minute) or Group 4 (BT; 3.4 +/- 0.3 minute). Regression analysis revealed that the onset times of the buffered solutions were significantly related to pCO2 (r2 = 0.81).(ABSTRACT TRUNCATED AT 250 WORDS)
